SWA termination OOPS

[SUNRAY]

Todays little RCD tripping problem, hardly DIY. This is the generator inlet and manual changeover pillar, the RCD is in the main supply (supplying armour into trunking) in an adjacent pillar.

The fault was elsewhere and eventually found to be earth bar metal theft. While waiting for a another man with keys I checked pillar, the adaptable box was lidded (like its neighbour and totally full of spider nest which extended to completely cover the armour. I found 49V DC between the armour and earthbar (from the equipments DC power supply).

I thought you'd like to see what some professional electricians think is OK.

Perfection!

If it were a 'professional electrician' (or, at least a 'professional professional' one) !

Mind you, there are some not far from here who have been known to promote (or, at least, endorse) the use of techniques other than 'SWA glands' for terminating SWA

I trust you're not comparing that with other methods of armour TERMINATION?

Excuse me for emboldening your message

Hmmm.....

The phase & neutral/earth from that split-con appear to go up into the enclosure above through different holes in the metal adaptable box. That's not the best of practices either!

It's SWA, brown and grey through one hole.

Is that necessarily a problem. If they are L&N?

I always think that there is no such thing as a professional electrician.

There are merely good electricians and bad electricians.
Obviously the above workmanship was done by a bad one.

I would have thought that a "professional electrician" would be an electrician (or 'electrician') who claimed that his/her profession was that of an electrician? - i.e. to distinguish from an 'amateur electrician', who made no such claims (like myself, and many others here).

There are merely good electricians and bad electricians.

There are -just as there are 'good' and 'bad' in relation to virtually any occupation/profession.

Obviously the above workmanship was done by a bad one.

... Indeed - but, as I said, only IF it were done by someone who regarded himself/herself as 'an electrician' of any sort!

You seem to be thinking of your own definition of 'termination' of a cable. To my mind, it refers to whatever one does with the ends of the conductors, no matter how good/bad/whatever that may be

That's an interesting point, to my mind terminating a wire or cable means connecting it to something. However a train terminal effectively connects to nothing and there is no reason a spare wire should not thought of in the same way.

To confirm; it's brown & grey as L&N through one 20mm hole and black as earth with a bond earth through the other 20mm.

I suppose that's literally true, but depends upon what the 'something' may be.

If you had an unused (but live) cable whose conductors you were 'putting for safety' into a connector block/whatever, would you not accepting that as 'terminating', even though the conductors were not electrically connected to anything? I think I would happily talk about 'terminating' into a terminal block in that situation, despite the absence of any electrical connection to anything).

Is that not what I wrote?

Sort of , but you talked of "train terminals" (and I suppose you could have chosen "airport terminals" and all sorts of other things, none of which have anything to do with cables or anything electrical - i.e. it's a total different usage/meaning of the word!) , whereas I brought it into the context of things electrical (which is what the discussion is about)
